I asked the same on TJC. Does somebody know a smart work around to get position when hiking in Lapland?

GPS location service doesn't work without cell tower ID. If I select Location and Device-only mode and set the phone in flight mode, GPS won't work. I assumed that would take longer to get fix but if flight mode is on, it won't ever get fix.

Really? Any idea why?
I guess it would have made sense in 1957 when superhets emitted a continuous tone but we are now a few years behind that.

Well the first stage mixer in modern receivers *does* leak out the PLL output, it is fairly low power but still... airlines tend to be fairly paranoid in these things.

Heck, last time I flew they told me I could not take pictures during landing/takeoff with my trusty old canon 10D DSLR!
Lucky I had my even trustier Pentax K1000 manual film SLR with me; when I explained the lady that this camera has no batteries whatsoever and works with springs and levers I was allowed to use it
